This device complies with RSS-210 of
Industry Canada. Operation is subject to
the following two conditions:
1. This device may not cause harmful
interference, and
2. this device must accept any interference
received, including interference that may
cause undesired operation.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
The Product label with FCC ID and IC
certification number can be found in the
battery case of the SmartKey.
Important notes on the use of KEYLESS-
GO
R The KEYLESS-GO key can be used like a
conventional key.
R You can combine KEYLESS-GO functions
with those of a conventional key, e.g.
unlock with KEYLESS-GO and lock with the
& button.
R Always carry your KEYLESS-GO key on your
person.
R Do not keep the KEYLESS-GO key together
with:
- electronic devices, e.g. a mobile phone
or another key
- metallic objects, e.g. coins or metal foil.
This can affect the functionality of
KEYLESS-GO.
R When locking and unlocking using
KEYLESS-GO, the distance between the
SmartKey and the corresponding door
handle must not exceed 3 ft (1 m).
R If the vehicle is parked for more than
72 hours, the KEYLESS-GO function is
deactivated. Pull the outer door handle and
switch on the ignition to reactivate the
KEYLESS-GO function.
R If the KEYLESS-GO key is removed from the
vehicle, it is possible that the system may
not recognize the SmartKey. The vehicle
can then not be locked or started using
KEYLESS-GO.
R If the KEYLESS-GO key has been removed
from the vehicle, e.g. if a passenger leaves
the vehicle with a KEYLESS-GO key:
- if the start/stop button is pressed or if
an attempt is made to lock the vehicle
with the locking button on the outer door
handle, the Key Not Detected message
appears in the multifunction display
- when the engine is running, the red Key
Not Detected message appears in the
multifunction display as you pull away.
Find the KEYLESS-GO key and change its
position in the vehicle. Carry the
KEYLESS-GO key in your shirt pocket, for
example.
R If you have started the engine with the
Start/Stop button, you can switch it off
again by:
- pressing the Start/Stop button again
- inserting the KEYLESS-GO key into the
ignition lock if the vehicle is stationary
and the automatic transmission is in park
position P.
R You could unlock the vehicle by mistake if
the distance between the KEYLESS-GO key
and the vehicle is less than 3 ft (1 m) and:
- an exterior door handle is hit by a water
jet
or
- you clean an exterior door handle.
R Bear in mind that the engine can be started
by any of the vehicle occupants if there is
a KEYLESS-GO key in the vehicle.80SmartKeyOpening/closing

Operating safety
General notes
GWARNING
Vehicles with HYBRID: ensure that you read
the "HYBRID" supplement. You may otherwise
fail to recognize dangers.
GWARNING
Making alterations to electronic components
can cause malfunctions.
Radio, satellite radio, amplifier, DVD changer,
navigation module, phone and voice control
are networked together. If one component is
not functional or if it has been incorrectly
removed/replaced, this could impair the
operation of other components.
This could seriously jeopardize the
operational safety of your vehicle.
We recommend that you always have
maintenance work on electronic components
carried out at an authorized Mercedes-Benz
Center.
GWARNING
In order to avoid distraction which could lead
to an accident, the driver should enter system
settings while the vehicle is at a standstill, and
operate the system only when permitted by
road, weather and traffic conditions.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your car covers a
distance of 44 feet (approximately 14 m) every
second.
COMAND supplies you with information to
help you select your route more easily and
guide you conveniently and safely to your
destination. For safety reasons, we
encourage the driver to stop the vehicle in a
safe place before answering or placing a call,
or consulting the COMAND screen to read
navigational maps, instructions, or
downloaded information.GWARNING
While the navigation system provides
directional assistance, the driver must remain
focused on safe driving behavior, especially
attention to traffic and street signs, and
should utilize the system's audio cues while
driving.
The navigation system does not supply any
information on stop signs, yield signs, traffic
regulations or traffic safety rules. Their
observance always remains in the driver's
personal responsibility. DVD maps do not
cover all areas nor all routes within an area.
